CIMERLI vs PYZCHIVA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CIMERLI (ranibizumab-eqrn) is a vascular endothelial growth factor (VEGF) inhibitor. It binds to VEGF-A isoforms (e.g., VEGF110, VEGF121, VEGF165) and prevents their interaction with receptors VEGFR-1 and VEGFR-2 on endothelial cells, thereby inhibiting angiogenesis and reducing vascular permeability.
Biosimilar to infliximab; a chimeric monoclonal antibody that binds to human tumor necrosis factor alpha (TNFα), neutralizing its activity and reducing inflammation.
0.5 mg (0.05 mL) administered by intravitreal injection once monthly (approximately every 28 days).
Intravenous infusion of 300 mg over 60 minutes on days 1, 15, and 29, then every 4 weeks thereafter.

Terminal elimination half-life: 5.9 days (range 4.0–7.5 days) in patients with neovascular AMD after intravitreal administration. This supports monthly or bimonthly dosing intervals.
Terminal elimination half-life approximately 21-25 days (mean 23 days), consistent with IgG1 monoclonal antibody clearance; supports monthly dosing.
Primarily eliminated via intracellular catabolism; urinary excretion of intact drug is negligible (<0.1%). Biliary/fecal excretion of intact drug is minimal. No renal or hepatic metabolism in the classical sense.
Primarily eliminated via the reticuloendothelial system; renal excretion of intact drug is negligible (<1%). Biliary/fecal excretion accounts for <5% as intact drug.
